With the "No Text While Driving app", you'll build a text answering machine. You'll process incoming texts to your phone, send out texts from the app, and have the phone speak aloud. You'll use the Texting component, the Text-to-Speech component, and the LocationSensor. You'll also store some data-- a custom text response message-- persistently.
